Which car license plate frequently gets featured in Balachandar flicks?

MSL 3636 (Sindhu Bairavi, Manadhil Urudhi Vendum are for sure, Am doubtful if Punnagai Mannan had it too. It is a light green Amby. I think a 3636 numbered car featured in Parthale Paravasam, although with a TN - xx series of license plate (TN-01 if am right).
